Abstract
A system for double-sided imaging on a continuous-web substrate having first and second substrate surfaces, the system including an imaging device including a toner-image bearing surface having selectively formed thereon first and second images. The system further includes a web-feeder system which selectively brings the first and second substrate surfaces into operative engagement with the toner-image bearing surface, to transfer thereto the first and second images, respectively, in accordance with a preselected imaging sequence.
Claims63
Image forming apparatus for double-sided imaging on a continuous-web substrate, having first and second surfaces on opposite sides of the substrate, comprising:
- an imaging device comprising an image bearing surface moving in a given direction and having selectively formed thereon first and second images;
- and
- a web-feeder system which selectively brings said first and second substrate surfaces into operative engagement with said image bearing surface, to transfer thereto said first and second images, respectively, in accordance with a preselected imaging sequence, wherein the first substrate surface engages the image bearing surface at a first transfer region and the second substrate surface engages the image bearing surface at a second transfer region, the second transfer region being displaced from the first transfer region in the given direction.
A method for double-sided imaging on a continuous-web substrate, having first and second surfaces on opposite sides of the substrate, using an imaging device including an image bearing surface, the method comprising:
- providing a series of first images on said image bearing surface;
- transferring each image of the series of first images from the image bearing surface to the first substrate surface;
- providing a series of second images on said image bearing surface;
- and
- transferring each image of the series of second images from the image bearing surface to the second substrate surface,
- wherein none of the images in the series of first images are transferred simultaneously with any of the images in the series of second images and wherein providing said series of first images and said series of second images comprises first, consecutively forming a plurality of first images and, then, alternatingly forming first and second images.
An imaging method according to 38 wherein transferring each images of the series of first images to the first substrate surface comprises transferring the images with a preselected spacing.
